Method: one unpaid request per listed endpoint. A 402 with a payment payload a client could parse counts. Nothing is paid.

2 x402-style payments from 2 distinct payers, $0.01 USDC in the last 7 days (Base, exact read)

This window shows the pattern of machine noise (few payers, dust amounts), so it does not count toward the evidence ranking.

All USDC received at this payout address: $0.01 (includes payments that are not x402)

Method: counted when the transaction carries a signed USDC authorization (EIP-3009), the settlement x402's exact scheme uses. Some non-x402 gasless sends use it too.

Reading: x402-style payments to this payout address on Base, exact read of the 7 days to 2026-10-05, every block of the window: counted when the transaction carries a signed USDC authorization (EIP-3009), the settlement x402's `exact` scheme uses. Some non-x402 gasless sends use it too; Sato Hub's own payer wallets are left out

Delivery is not measured. We never send a payment, so we never observe what a paid call returns. Unknown means we hold no reading, not that anything failed.
